[Mina] JMX instrumentation

| Hi,
it seems that Mina JMX instrumentation is planned, but I don't know when.
I actually need some performance counters (throughput, total nr of connections,
current and max nr of concurrent connections...) for an application based on
Mina.
I am going to spend some time on this, and I could do it in Mina code as well,
so that everyone can benefit.
But I would need feedback on needed counters and some help for the best places
to probe.
What do you think of this ?

That's sound very interesting 
I'm working on implementing a fail-over service and replication on my
MINA bassed server, and I need to monitor some parameters (different
MINA Protocol stacks status, CPU usage , free RAM and dozen of custom
parameters) for triggering a service migration (killing the running
service on the main server and start the service on the backup server).
I'm really new to JMX instrumentation but i think it could really help
me, so I'm willing to help to get it into Mina.

JMX is really simple, as you will notice.
I need counters providing qualitative and quantitative information
about server
load.
A first good data would be the time a SessionManager is idle (blocked on
Selector.select()). Then, workTime = lifeTime - idleTime (I don't know if
vocabulary is the more appropriate one) This workTime is valuable for
statistics.

Wow, thank you so much for your great plan.

JMX integration is planned to be included in version 1.1:
http://issues.apache.org/jira/browse/DIRMINA-29
We could keep talking about it there by leaving comments. I'll start
enumerating the requirements.
Thanks,
Trustin
